printer won't print black

[Eddie G]

I have an HP photosmart 7550 and I just changed the black ink cartridge and
printed a calibration page and it looked fine. I went to print a Word
document and the print head was moving like it is printing but the page came
out blank. I changed cartridges and it happened again, so I don't think
it's the cartridge (unless I happened to have 2 bad carts, but what is the
chance of that?). The HP toolbox says the ink level is full.

Any ideas?

Thanks!!

If the calibration page is consistently good then the problem is unlikely to be
printhead or printer related.
How does the Windows Test page look (assuming you are using Windows)?

Have you tried printing anything else? Could be the Word document got
screwed up and it is printing white text or some strange occurrence. Try
printing from another program, such as this post from your newsreader.

The words "windows xp printer test page" came out light and there is nothing
else on the page, although as I said the printer "thinks" it is printing as
I can hear the print head moving.

I guess I can have 2 bad cartridges in a row, right?

Sounds like it....
The light text at the top of the page is probably being printed in colour (not
too sure, but a composite black made from the colour cartrdige), the rest of
the page should be black ink only so it looks like the cartrdige is bad. Try
pressing the printhead onto a folded damp paper towel, you should get a good
solid black rectangle of ink on the towel, if not the cartridge is bad.

I did pressed the printhead on a paper towel and got the ink rectangle, put
it back and printed this post and the black is being printed by the colors.
I figure I should call HP support...

Yes Eddie, I agree especially if the printer is in warranty.
